Types SCR and SCR-DIndoor current transformers

Instrument transformers

Product features − 600 volt, indoor, 10 kV BIL − 25 - 400 Hertz − Primary amperes: 50 - 5000 − Mechanical rating: 180 x rated current − Thermal rating: 80 x rated current, one second − Continuous current rating factor:

2.0 @ 30°C ambient 1.5 @ 55°C ambient

ApplicationThe SCR and SCR-D current transformers are used as the source of current for relaying and metering. The deeper case SCR-D is used when high burden relaying and metering is required.

Construction featuresThe ring-type core is insulated and toroidally wound with a fully distributed secondary winding. The protective case, made of an impact-resistant polycarbonate, is ultrasonically sealed.

Secondary terminalsSecondary terminals are 8-32 brass terminal screws with hardware. Space is available for a maximum of five terminals to accommodate multi-ratio designs.

CurvesSaturation, overcurrent, ratio correction factor, and phase-angle curves are available upon request.

Test reportsIEEE test reports are stored electronically and can be e-mailed in various formats at the time of shipment.

StandardsThis unit meets all applicable IEEE and NEMA standards and is a UL Recognized Component.
